Get answers to common questions about NSG's security guard and commercial cleaning services in Greater Cincinnati
Commercial Cleaning
Most commercial cleaning companies send crews and hope for the best. We're different. Operations managers visit your facility weekly to inspect work quality and address issues before you notice them. Site-trained backup teams prevent missed shifts when someone calls off. And you can reach our local management 24/7, not corporate voicemail. We've been family-owned in Cincinnati since 1988, which means accountability goes straight to ownership.
We handle complete facility cleaning: nightly janitorial service, day porter programs, carpet cleaning, hard floor care and maintenance, restroom sanitization, high-touch disinfection, and trash removal. Our commercial cleaning programs are customized for your facility's needs and schedule, not one-size-fits-all packages.
Our commercial cleaning services cover corporate offices, medical facilities, multi-tenant buildings, industrial spaces, warehouses, government buildings, and apartment communities throughout Greater Cincinnati and Northern Kentucky. From 5,000 square feet to 500,000+ square feet, we scale to your facility's size and complexity.
We prefer 30 days from contract signing to start date. This allows our recruiting team to properly source, screen, and train personnel specifically for your facility. Service quality depends on proper preparation. Rushing the process leads to problems. That said, we can accommodate urgent needs when necessary.
Yes. Day porters maintain high-traffic areas during business hours: lobbies, restrooms, break rooms, conference rooms. They handle immediate cleaning needs, restock supplies, respond to spills, and keep your facility presentable when clients and employees are there. This service is critical for buildings with significant daytime activity.
Weekly site visits by operations managers, documented inspections, performance tracking technology, and direct management accountability. Quality doesn't maintain itself. It requires systematic oversight. We built our commercial cleaning company around preventing the quality drift that happens with most providers.
Security Guards
We provide professional unarmed security guards for: front desk/concierge, mobile patrols, access control, visitor management, parking lot security, patrol verification, and incident response. Our security guard services are available 24/7 with coverage customized to your facility's specific requirements and risk profile.
Site-trained flex teams. Backup security guards complete full training on your facility before primary staff call off. When absences happen, replacements already know your building layout, access procedures, emergency protocols, and client expectations. You never go unprotected because we couldn't find coverage.
Yes. All security guards complete professional security training, hold required state certifications, undergo background checks, and receive site-specific training on your facility's procedures, emergency protocols, and client expectations before deployment. Training isn't one-time. We provide ongoing development.
Our security guards protect corporate offices, distribution centers, warehouses, manufacturing facilities, government buildings, healthcare facilities, data centers, multi-tenant properties, and apartment communities throughout Greater Cincinnati. We've protected Fortune 25 companies and small businesses. Experience spans all facility types and security requirements.
GPS-tracked patrols, checkpoint scanning systems, daily activity reports, and incident documentation with photos. Technology provides objective proof of service delivery. You're not relying on self-reported logs. Operations managers review data to verify security guards complete assigned duties.
Yes. 24/7/365 management hotline connects you directly to NSG supervisors with authority to make decisions and deploy personnel. Emergencies don't wait for business hours, and neither does our management team. You get real people solving real problems immediately, not voicemail.

When one of our employees recently tested positive for COVID-19, we asked the janitorial team to do deep cleaning in that area. I was very impressed with how responsive and thorough the team was and appreciated how friendly they are too. They always have a smile and are quick to respond.
